Application filed September 2, 1915. Serial No. 48,631.

To all whom it may concern:

Be it known that I, CHAnLns L. HnIsLnn,

a citizen of the United States, and resident I improved means for moving the coal forwardly in the bin to bring it within convenient reach of the fireman.

The invention herein shown is of the same general character as the invention shown in my pending application Serial No. 48,630, its object being to provide a different form of construction of an adjustable'shoveling platform for the fuel bin of the tender, and of the operating mechanism for driving the coal pusher.

The invention consists in a structure such as is hereinafter described, and as illustrated in the accompanying drawings, in which- Figure 1 is a detail vertical central section of a locomotive and its tender with the invention applied; Fig. 2 is a detail section on the line 22 of Fig. 1; Fig. 3 is a detail plan view of the tender; and Fig. 4 is a detail plan section of the pusher operating mechanism.

The side wall of the fuel bin ofthe tender is represented at 10, and its rear inclined wall at 11. The floor 12 of the tender extends forwardly from the rear wall'll, and there is provided a shoveling platform 13, hingedly connected to the floor 12 at 14, and having an upwardly flexing joint 15. At each side of the forward section of this platform, and secured thereto at or adjacent to the joint 15, there is a hook 16 adapted to take over a stud 17 projecting inwardly from the side wall 10. Asecond hook 18 is attached to the forward section of the platform 13 and adjacent its forward edge, be ing adapted to engage a stud 19 fixed in the side wall 10 and serving as an additional support for the platform when in its elevated position. By disengaging the hook 18 from the stud 19, and the hook 16 from the stud 17, the platform may be lowered to the floor 12. The joint 15 may be so formed as to serve as a stop to limit its downward flexure and thereby serve as an additional support for the forward section of the platform when elevated to its extreme limit.

The mechanism provided, for advancing the coal to the shoveling platform comprises a head 20, adapted to reciprocate over the tender floor 12, its width being substantially the same as the bottom of the bin,-a plate 21 extending backwardly from' the upper edge of the head, and downwardly projecting side flanges 22, 23, and a rear flange 24 for strengthening the pushing element and excluding coal from beneath it. The flange 24 rests and slides upon the rear inclined I wall 11. ofthe fuel bin.

l/Vithin the rear end of the pushing element there is securely fixed a cross-bar 25, which preferably extends its entire width. A pair of links 26, 27, connect the cross-bar 25 with a nut 28, in threaded engagement with a screw-rod 29 which is journaled at its upper end in a box 30, securely attached to the wall of the fuel bin. A worm gear 31 is keyed upon the upper end of the screwrod 29, and meshes with a worm shaft 32 extending horizontally and journaled in suitable boxes 33, 34, fixed to the fuel bin wall. A pair of bevel gears 35, 36, are loosely mounted on the shaft 32, and are in constant engagement with a bevel gear 37, driven by a suitable motor (conventionally shown at 38 as a steam. turbine).

A double faced clutch 39 is splined upon the shaft 32 between the gears 35 36, and is adapted to lock them to the. shaft 32 in al-U ternation for the purposeof advancing and retracting the pusher head. A shipper lever 4, in the form of a bell crank,cooperates with the clutch element 39, and is pivoted at 41 to the tender wall. A red 42 connects the free arm 43 of the shipper lever with the nut 28, and is in sliding engagement with the latter, being provided at its lower end with a head 44. Preferably the connection between the rod 42 and the lever arm 43 is by means of a knuckle 45, pivoted ing the shaft 32 to be reversed in its direction of movement for the purpose of retracting the pusher head. As the pusher head approaches the limit of its backward movement the nut 28 engages the knuckle 4,5 and swings the shipper lever on its pivot to engagethe clutch member with the gear 35, and thereby again cause the advance movement of the pusher head. A pull rod 47, connected to the shi'pper lever by means of a link 48 and bell-crank 49, affords means for changing the direction of move- I ment of the pusher head atthe will of the operator. A suitable housing 50, covers the gear mechanism, shipper lever and screws rod, and ahousing 51 covers the links 26, 27, and the nut 28, and slides Within that 1 part "of the housing 50 which incloses the forward end of the tender where it convenient of access.

screw rod. Steam may be led to the motor 38 by any suitable piping, such as shown at 52, and a throttlevalve 53 may be controlled by a valve rod 54 extending to the will be I claim as my invention-- 1 1/ A locomotive tender having a fuel bin,
